      8title: TI J721e System Controller Registers R/W Device Tree Bindings
      9
     10description: |
     11  This represents the Control Module registers (CTRL_MMR0) on the SoC.
     12  System controller node represents a register region containing a set
     13  of miscellaneous registers. The registers are not cohesive enough to
     14  represent as any specific type of device. The typical use-case is
     15  for some other node's driver, or platform-specific code, to acquire
     16  a reference to the syscon node (e.g. by phandle, node path, or
     17  search using a specific compatible value), interrogate the node (or
     18  associated OS driver) to determine the location of the registers,
     19  and access the registers directly.
